Generations

Works together

How the cisco Nexus 9000 Nexus 9508 connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

FAQ

How does power supply redundancy function in the Nexus 9508?

It accommodates up to eight 3000W or 3150W power supplies offering N+1, N+N, or combined redundancy modes.

Can older generation line cards mix with newer Cloud Scale line cards?

Line cards must be matched with compatible fabric modules; modern GX/GX2 line cards require the corresponding generation fabric modules.
